Hi,

I have some problems producing postscript plots using rkward (versions 0.3.6
and 0.4.5). Relatively simple plots like


postscript()
plot(1:10,1:10,type="l")
dev.off()


which gives just a diagonal line fail. A file "Rplot.ps" is saved, but invoking
a ghostscript interpreter gives an error like


ERROR: /undefined in 595,00

ESP Ghostscript 815.02: Unrecoverable error, exit code 1


I get the same for other plots. If I save the code to a file and load it directly
into R (2.3.1) I get a perfect postscript file.
This behaviour seems to be basically the same for every output-device using
ghostscript (e.g. pdf or bitmap) while functions like png() are working
perfectly.
Since I need to print the plots, pixel-oriented formats like png and jpeg are
not really usefull.

Do I make something wrong? Or is this functionality just not implemented yet?

I use rkward with KDE 3.5.6 under Kubuntu Edgy.

Regards,
Matthias
